Trapezoidal screws

Trapezoidal screws

Trapeziodal screws (hereinafter also Tr screws) with metric trapezoidal thread (according to ČSN 014050)
are standard structural components used as self-locking transition of
the rotary motion to linear motion with low efficiency, given by the
principle of their construction, by the lubrication and by the material
of the friction thread surfaces.

These lead screws bear only axial load
and relevant torque whereas backlash between the screw and the nut
should be decreased by special construction.

Trapezoidal
screws are supplied as a complex assembly with matched nut or nuts
according to the request of the customer. Their material, application,
lubrication and adjustment of backlash, which occurs during the
operation, are determined by the custom practice of the particular
customers and it is not solved by the manufacturer, which provides only
consulting and advisory services.
